CURTAINH'PQLE.

sPEcIFIcATIoN forming 'part of Letters Patent No. 638,179, dated November as, 189e.

Application llel August 17, 1899.

To all whom t may concern:

Be it known that I, J ULIUs F. GEBHARDT, a citizen of the United States, residing at No. 203 Henry street, in the borough of Brooklyn, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Curtain- Poles, of which the following is a specification.

The object of my invention is to provide a new and improved curtain-pole which is simple in construction, strongand durable, and which permits of readily shifting the curtains without any undue strain on the material of which they are composed.

In the accompanying drawings, forming a part of this specification and in which like letters of reference indicate like parts in all the views, Figure l is a side view of my improved curtain-pole and part of a curtain thereon. Fig. 2 is an enlarged vertical transverse sectional vie/w through my improved curtain-pole and a suspension-pin thereon. Fig. 3 is a similar view of the pole with the saw-kerf. Fig. 4L is a detail transverse sectional view of the track. Fig. 5 is a vertical transverse sectional view of a hollow metal pole. Fig. 6 shows a modification.

The pole A, preferably made of wood, is provided in its bottom part with a longitudinal, preferably radial, saw-kerf B, extending the entire length of the pole and adapted to receive two sheet-metal strips O, which are inserted lengthwise into the saw-kerf in such a manner that the lower edges of said strips project beyond the bottom of the pole, said projections being curved laterally and from each other to form the oppositely-extending iianges D, the free edges of which are curved upward and toward each other, thus forming tracks. In case the pole is made hollow of sheet metal, as at A in Fig. 5, it is provided at the bottom with two lips C', extending lengthwise and also curved outward in the manner described above to form tracks D.

Safety-pins F. or other like suspension devices are attached to the upper edge part otthe curtain a, and the upper member b of each such safety-pin or suspension device is provided with two upwardly-extending arms F, which are curved outwardly and then inwardly substantially in the form of a volute of such size as to :tit into a track D or D', the

Serial No. 727,573. (No model.)

curved bottom part d d of the volute being adapted to rest upon the upper surface of the track D. The curved arms F can be passed upon the tracks D or D, at the open ends of the latter, so as to embrace the tracks loosely and can easily be shifted lengthwise thereon. The upper edges I-I of the strips C are bent slightly from each other, as shown in Fig. 4., so that when the strips are inserted lengthwise in the saw-kerf these bent edges are jammed in the kerf, and thus hold the strips in place firmly and securely on the pole A.

As shown in Fig. 6, the tracks D may be reversedthat is, instead of being curved from each other outward and upward they may be curved from each other outward and downward and then slightly upward toward each other, as at D3 in Fig. 6, and such tracks may be located in a longitudinal groove A4 in the pole. The arms F of the pins E must be curved accordingly-that is, reversed-as is also shown in Fig. 6.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a curtain-pole, of 'two outwardly and transversely curved 1ongitudinal trough-shaped tracks on the under part of the same and curtain-suspending pins each having two upwardly-extending arms curved to form two volutes, to rest upon said trough-shaped tracks, substantially as herein shown and described.

2. The combination with a curtain-pole having a longitudinal saw-kerf in its under part, of two metal strips inserted longitudinally in said kerf and having their upper edges bent slightly from each other and having flanges forming tracks on their lower edges, substantially as herein shown and described.

3. The combination with a curtain-pole having a longitudinal saw-kerf in its under part of two metal strips inserted longitudinally into said kerf and having iianges forming tracks on their lower projecting edges, substantially as herein shown and described.

Signed at New York, in the county of New York and State of New York, this 12th day of August, A. D. 1899.
